python decrease gap between subplot rows

# Short answer:
# If you have too much white space between rows (or columns) of a figure
# with subplots, you can either shrink the vertical (or horizontal) 
# dimensions of the figure with figsize so that they get more "squished"
# together, or you can adjust the margin around the subplots
fig, ax = plt.subplots(rows, cols, figsize=[24,12])
plt.subplots_adjust(bottom=0.3, top=0.7, hspace=0)

Here is what the above code is Doing:
1. We’re creating a figure with subplots.
2. We’re adjusting the margins around the subplots.
3. We’re adjusting the spacing between the subplots.
